Abstract :
A high-speed pattern generator system having a 1.2-GHz NRZ (non-return-to-zero) data rate capability is introduced. The phase-locked loop per pin architecture has independent timing and adjust and utilizes a Nd:YAG laser system as a precise timing reference. The per pin architecture has a delay range of +/- 1 data cycle with 10-ps placement resolution. This delay range is implemented with a combination of analog and digital techniques yielding a data edge jitter of <10 ps RMS. Also presented are algorithms for pattern length to enhance throughput for a sampling measurement system
